Renal arteries

The treatment of peripheral vascular disease is a complex area that requires a great deal of experience and skill. Most aspects of vascular arterial disease can now be managed endovascularly (from inside the artery). Renal arterial disease is dealt with almost exclusively by this method. The renal arteries are susceptible to formation of plaque. In a small but important number of patients suffering from uncontrolled hypertension, the cause is a stenosis of >60% in one or both of the renal arteries. If the blood flow to the kidneys is restricted by way of a stenosis, the kidneys alter certain chemicals in the body and also retain water forcing the patients blood pressure higher and higher. You may initially be referred for a renal artery duplex to assess for evidence of renal artery stenosis or to look for other signs of kidney disease. The treatment for renal artery stenosis is ballooning with or without stenting. This is generally only performed when the stenosis in one or both of the kidneys reach higher than 70% with signs of renal impairment. As a cardiologist managing and treating hypertension day in day out, Dr Sharpe is best placed to know when and how your renal artery disease should be treated. Dr Sharpe is very experienced in the area of renal artery balloon angioplasty and stenting. Together with his extensive cardiac experience he can offer a complete assessment and treatment plan to improve your arterial health.  Treatments can take only a few hours in hospital and patients can in most cases go home the same or next day. * There are also new treatments on the horizon for hypertension. This involves de-activating the nerves fibres that surround the renal arteries. This treatment is showing great promise for those patients with uncontrolled and life threatening hypertension that are not responding to the drug therapy or are suffering severe side effects from the drug treatment. We wait with anticipation for renal denervation to become available in the private health system. .
